40 Claim.

This invention relates to new and useful improvements in means for and method of permanently waving hair. This application is a continuation of application Serial No. 491,781, filed October 28, 1930.

One object of this invention is to provide a hair waving device wherein a chemical reaction is utilized for creating a vapor of sufficient heat to permanently wave the hair.

Another object of the invention is to provide a permanent hair waving device wherein means are provided for completing the operations required in the waving of hair, without the application of external heating devices.

Another object of the invention resides in the provision of a permanent waver which can be easily handled and manipulated in operation and which does not require any fastening means for maintaining the same intact on the hair while the hair is being treated thereby.

These and various other important objects and advantages of the invention will be more fully described hereinafter.

In the drawings:

Fig. 1 represents a side elevation of the waver as in use;

Fig. 2 represents an inside plan view of the waver with theparts in the positions they assume when the waver is about to be wrapped around the preformed tress;

Fig. 3 represents a longitudinal sectional view through the waver when in use;

Fig. 4 represents a cross sectional view taken in the plane of the line 44 of Fig. 3;

Fig. 5 represents a top plan view of the head protecting gasket;

Fig. 6 represents a top plan view of the scalp shield;

Fig. 7 represents a bottom plan view of the perforator; and

Fig. 8 represents a side elevational view of the perforator.

Referring to the drawings, wherein like numerals designate like parts, the numeral 5 indicates the winding implement which may be made up in the usual way, said implement comprising a barrel 6 and a hand operated stem 1 extending therethrough, to one end of which the hair may be tied as shown in Fig. 3 and denoted by the numeral 8. The foregoing is conventional and the following represents the invention which is associated therewith in the permanent waving of hair.

Figs. 5 and 6 also show conventional fixtures. the numeral 9 representing a slit gasket through The combined sheets the central opening to of which the hair is passed. The scalp shield is denoted by H. The gasket 9 serves as a protector for the head by insulating the heat from the scalp.

In carrying out the present invention, the sheet I! of some suitable material as paper has the sachet l3 suitably secured thereto adjacent to one edge thereof. This sachet is of impervious material as metal foil and it contains a suitable chemical l6 such as calcium oxide or 10 calcium oxide compounds, which is intended to be combined with a liquid, such as ammonium hydroxide, to develop heat sufficient to permanently wave the hair. This ammonium hydroxide may be applied to the sachet by providing an apron l4 adapted to be moistened by the said ammonium hydroxide; the sachet being perforated as shown at l5 to permit the moisture from the apron M to reach the heat generating chemical contained in the sachet.

A perforating implement may be provided for perforating the sachet I3, which implement is shown in Figs. 7 and. 8 of the drawings and comprises a backing ll, prongs I 8 and handle l9.

An outer sheet 20 may be secured to the sheet l2, the outer sheet being preferably of some impervious material such, for instance, as metal foil.

I do not wish to limit myself to the particular heating chemical employed nor to its co-reagent. One way of utilizing the hair waving device would be as follows: The apron I4 is moistened and the preformed tress is placed thereon, as shown in Fig. 2.. The apron is then wrapped around the tress and the sachet I3 is perforated.

I2 and 20 are then wrapped around the preformed tress and apron l4 and the moisture from the apron is transmitted to the heating chemical l6 through the perforations I5, thereby causing the chemical to react exothermically to generate sufficient heat to permanently wave the preformed tress.

The sheets I! and 20 may be clinched at their upper and lower ends in the manner shown in Fig. 1 to prevent the escape of the vapor generated within the device. The nature of the sheet 20 will permit the device to retain its wrapped condition around the preformed tress during the steaming or heating operation.

It will be seen that no source of outside heat 5 is required in connection with my improved hair waving device and that the expense is materially reduced owing to the fact that the expense of repair ordinarily required in devices where outside heat is used, is eliminated.

While the foregoing specification sets forth the invention in more or less specific terms, it will be understood that numerous changes in the shape, size and materials may be resorted to without departing from the spirit and scope of the invention as claimed hereinafter.

It will be understood that the term perforable" as used herein, refers broadly to the character of the material constituting the exposed face of the envelope, whether said face is perforated at the time of manufacture or left imperforate until the time of use, or perforated at some intermediate time.
